Perry, you'd learn a lot from the guy. Good businessman. Nice guy too, but a stickler for quality. You could leverage your mechanical skills (rather than starting over on something else) while not being locked in to them. Besides, you'd be TIGging in no time! Good skill to have for so many reasons, no matter WHAT you do.

It would make a good part time adjunct job for some other day job.... Never know what it could build into.
